Why Is My Water Bill So High This Month? 10 Common Reasons (and How to Fix Them!)
Ever opened your water bill and done a double-take? If you’re a Murrieta homeowner, you’re not alone. Let’s look at the most common causes of water bill spikes—and how to get them under control.
🚰 1. Sneaky Leaks in Faucets or Toilets
A tiny drip might seem harmless—but it adds up fast. One drip per second can waste up to 3,000 gallons a year. And a running toilet? That could cost you 200 gallons a day.
Quick fix: Do a dye test in your toilet tank. If the color seeps into the bowl, it’s time to replace the flapper.
2. Hidden Pipe or Slab Leaks
Some leaks don’t make a sound. Look for soggy spots in your yard, moldy smells, or your water meter moving even when everything is off. If it’s more than a drip, it’s time to call the pros.
🛁 3. Old Toilets and Fixtures
That vintage toilet might look cool—but it uses nearly 3x the water per flush compared to modern low-flow models. Upgrading to WaterSense® fixtures can shave off gallons every day.
4. Outdoor Irrigation Gone Rogue
Sprinklers and drip lines can quietly waste water when misaligned, broken, or over-scheduled. A single faulty sprinkler head can dump 25 gallons in 10 minutes.
🏖️ 5. Seasonal or Lifestyle Spikes
Did you fill a pool? Water the lawn more often? Have extra guests? These can add hundreds of gallons to your bill without you realizing.
